Nov. 8 (UPI) -- Although former Vice President Joe Biden is projected to become the 46th president of the United States, races in four states have not yet been decided.
In Georgia, Biden maintained a 10,300 vote lead over Trump with 99% of the vote counted.
A recount is expected to determine who will ultimately claim the state's 16 electoral votes, as the recount process is automatic if the gap is 0.5% or less.
Former Georgia gubernatorial candidate Stacey Abrams told CNN Sunday that she believes Biden will maintain his lead in the state, even in the face of a pending recount.
"The results will be the same, Joe Biden has won the state of Georgia," Abrams said.
Trump led the battle for North Carolina's 15 electoral votes on Sunday by 75,400 votes, with 98% of votes tallied.
With 97% reporting in Arizona, Biden held a lead of 19,300 votes.
With 47% of votes counted in Alaska, Trump leads by 108,200 votes.
Former President George W. Bush on Sunday congratulated Biden on his win and praised Trump for "a hard-fought campaign," adding that while he "has the right to request recounts and pursue legal challenges," Biden's victory was clear.
"The American people can have confidence that this election was fundamentally fair, its integrity will be upheld and its outcome is clear," Bush said.
In 2000, Bush was declared president 37 days after the election when a U.S. Supreme Court ruling paved the way for a win over Democrat Al Gore. The high court ruled against continuing a hand recount in Florida. Ultimately, Bush won Florida to capture the state's electoral votes and the presidency.
Like in 2000, the Democrat this year won the popular vote -- by more than 4 million ballots.
Trump has not conceded the race and his campaign has issued a number of legal challenges to results in states that have been called in favor of Biden or where he holds a lead.
On Sunday morning, he shared various quotes on Twitter alleging issues with the way some votes were tabulated as he continued his efforts to challenge the result of the election.
First lady Melania Trump also took to Twitter to comment on the election, repeating the president's claims that "illegal" votes were cast.
Former Republican presidential candidate Sen. Mitt Romney, R-Utah, said he has not seen evidence of widespread voter fraud in the United States.
"I do believe, however, that is destructive to the cause of Democracy to suggest widespread fraud or corruption. There's just no evidence of that at this stage," he told CNN's State of the Union. "And I think it's important for us to recognize that the world is watching."
Condoleezza Rice, a well-known figure of the Republican Party and former secretary of state, congratulated Biden late Sunday and called for unity among Americans.
"Congratulations President-elect Joe Biden and Vice President-elect Kamala Harris, and the American people who voted in record numbers showing the strength and vibrancy of our democracy," she tweeted. "Now, let's come together for the common good with empathy and respect for each other."
The Trump campaign filed a lawsuit on Saturday, alleging that poll workers did not notify in-person voters when the electronic ballot tabulation machines detected an "overvote," indicating that a voter had selected more than the number of candidates allowed in a certain race.
